Etheric plane

Similarly, according to the Rosicrucian writings of American occultist and mystic Max Heindel^[5] there is – in addition to the solids, liquids, and gases which compose the Chemical Region of the Physical World – a finer grade of matter called ether that permeates the atomic structure of the earth and its atmosphere. It is disposed in four grades of density and is considered to be a kind of physical matter (the blue haze seen in mountain canyons is said to be in fact ether of the kind known to occult investigators as chemical ether). Associated there is also a type of spiritual sight, that man will eventually develop, called etheric vision.^[6] Ether is reported to be of four kinds, or grades of density in our planet Earth; their names (from the lowest or most dense to the highest or most subtle one) and their relation to the human being, from the point of view of these Esoteric Christian teachings, is as following:^[7]

• the "Chemical Ether": both positive and negative in manifestation and it is related to the assimilation and excretion processes;
• the "Life Ether": has also a positive and negative pole and it is related to the forces of propagation;
• the "Light Ether": the positive pole is related to forces which generate blood heat in the higher species of animal and in the human being and the negative is related to the forces which operate through the senses (passive functions of sight, hearing, feeling, tasting, and smelling);
• the "Reflective Ether": the medium through which thought makes an impression upon the human brain and this ether contains pictures which work as reflections of the Memory of Nature found at the World of Thought.
